# Hereafter should be "server" or "peer" statements to configure

# other hosts to exchange NTP packets with. Peers should be selected
|
||
|
|
# in such a way that the network path to them is symmetric (that is,
|
||
|
|
# the series of links and routers used to get to the peer is the same
|
||
|
|
# one that the peer uses to get back. NTP assumes such symmetry
|
||
|
|
# in its network delay calculation. NTP will apply an incorrect
|
||
|
|
# adjustment to timestamps received from the peer if the path is not
|
||
|
|
# symmetric. This can result in clock skew (your system clock being
|
||
|
|
# maintained consistently wrong by a certain amount).
|
||
|
|
#
|
||
|
|
# The best way to select symmetric peers is to make sure that the
|
||
|
|
# network path to them is as short as possible (this reduces the
|
||
|
|
# chance that there is more than one network path between you and
|
||
|
|
# your peer). You can measure these distances with the traceroute(8)
|
||
|
|
# program. The best place to start looking for NTP peers for your
|
||
|
|
# system is within your own network, or at your Internet Service
|
||
|
|
# Provider (ISP).
|
||
|
|

|

|
|
# Ideally, you should select at least three other systems to talk
|
||
|

# NTP with, for an "what I tell you three times is true" effect.
